STOVE.

Patented Feb. 1, 1921.

Application filed m 11, 1918,.Serial N0. 2&4;421. 'Rnewfltl October a, 1919." Serial No. 325,391.

To all whom it may concern:

Belt known that 1,.VVILLIAIVL J. Base, a citizen of the UnitedStates, and residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and Im? proved Stove, ofwhich the following is a specification.

This invention relates to stoves znflapted for fawning kerosene, gasolene or alcohol, and its object is to provide a structure wherein the burner can be quickly. and easily removed and replaced. with the least possible work. i

This invention consists in the details of construction illustrated in the accompanying drawings and particularly pointed out in the claims.

In the drawing,iFig'ure 1 is a view, partly in section and partly in elevation of a. burner embodying the present invention. Fig. 2 is a plan showing the arrangement of three burners. Fig. 3 is a plan on a reduced scale of the vaporizer used in the burner shown in Fig. 1. Fig. f is a similar plan of the burner base.

Similar reference characters refer to like parts throughout the several views.

The burner shown in the drawings embodies a perforated inner chimney 1, a per forated outer chimney 2 and a cowl. 3 sup ported by rods 4 that extend across through the chimneys. The vaporizer preferably consists of an outer side 5 and a trough 6 formed out of the same piece of metal, and

an inner side 7 and bottom 8 also pressed up of a single sheet of metal. These two parts of the vaporizer may be welded together so as to render them integral. A wick 9 fits around the inner side 7 of the vaporizer. The edge of the outer side 5 of the vaporizer is preferably formed into a shelf 10 to support the outer chimney 9, while a ring 11 may constitute a bearing member between the side 7 and the inner chimney.

The cup-shaped burner base consists of a bottom 13, a perforated inner cylinder 14., a perforated shelf 15, and an outer cylinder 16. The bottom 13 is provided with an annular head or rib 17 which rests on the chan nel bar 18 which constitutes the main cross frame of the stove and on which all the burners are mounted. The channel bar and the bottoms 13 of the base and of the vaporizer are formed with alined holes to receive the bolt 19. The thumb nut 20 on the upper end of this bolt can be reached by lifting oil" the cowl and the two chimneys whereupon the remainder of the burner may be removed. The shelf 10 on the outer side 5 of the vaporizer has outwardly projecting lugs or fingers which position the va porizer and chimneys relative to the base; The trough of the vaporizer may beformed with an annular rib to rest on the shelf 15. A pipe 24: connects the vaporizer to a source of fuel.

Gne of the objects desired in the burner embodying the present invention is to keep the vaporizer as hot as possible. The aircular ring 1 1 shown in the drawing spaces the vaporizer from the stationary support 18 and prevents, as far as possible, the heat from the vaporizer passing to the stationary support. if the vaporizer were mounted directly on the stationary support there would be a great amount of heat transmitted by the vaporizer to the support, and because of the fact thatthe stationary support necessarily must be made heavy and large so as to give it sufficient strength to support the three or four burners which are often placed in one stove, and therefore have a large radiating surface, the heat of the vaporizer would be rapidly dissipated.

The details and proportions of the various parts of the burner may all be changed Wllll'ifillll departing from the spirit of my invention as pointed out in the following claims.

I claim 1. In a stove, the combination of a support, a cupehaped burner base mounted thereon, a vaporizer mounted on and extending into said base and comprising perforated co-anial sides and a bottom, eonccntric chimneys rcmovably mounted on said vaporizer, the support and the bottoms of the base and of the vaporizer being formed with. alined holes, and a bolt extending through said holes to secure the vaporizer and base to the support.

2. In a stove, the combination of a channel iron support and a bolt extending upwardly thereon; a base mounted on the sup port consisting of acircular bottom having a central hole through which the bolt extends, a perforated cylindrical portion extending upwardly from the bottom, an annular shelf at the upper edge thereof and a second cylindrical portion extending upwardly from the outer edge of the shelf; a

vaporizer mounted on said base and comprising a perforated bottom having a cen-;

tral hole through which the bolt extends, a, trough, and eo-axial perforated sides integral With the trough and bottom; inner and outer'chimneys supported by the sides of the vaporizer and freely removable therefrom, and a nut on the upper end of the bolt adapted to be screwed down onto the bottom of the vaporizer to hold the vaporizer and base in position.

3. In a stove, the combination of a support having a flat top provided With a hole, a burner base, a vaporizer resting on the burner base, a bottom plate. for the vaporv izer, said base and plate formed With holes adapted to aline with the hole in the support,

7 a bolt extending through said three holes and a nut on the bolt adapted to secure the vaporizer and base to the support, and chimneys extending upward from the vaporizer. A

4c. In a stove, the combination of a support, a circular intermediate member resting upon the support, a vaporizer mounted on the intermediate member and positioned thereby above the support so as to permit air to flow between them, a diaphragm extending across the space within the vaporizer not higher than the level thereof, and a bolt extending up from the support to the diaphragm, to secure the several parts in predetermined position.

5. In a stove, the combination of a stationary support, a vaporizer mounted on the support and comprising an annular chamber and a diaphragm, concentric chimneys mounted on the vaporizer above said diaphragm, and a bolt extending through a hole in the support and a hole in said diaphragm to secure the vaporizer in predetermined position on the support.

6. In a stove, the combination of a burner comprising a trough-shaped vaporizer, up-

wardly extending pcrfo ated chimneys and I a diaphragm; a stationary support, a cylindrical member resting on said support and upon which said burner is mounted and by which the burner is spaced from the support, and a bolt extending through holes in said support and in said diaphragm to secure the burner to said support.
